RIM FOR. WHEELS.

Specification of Letters Patent.

Application filed August 27. 1913.

Patent ed An 25, 1914:.

Serial No. 786.875.

T011 when: it 'n /u coin-era Be it known that l. PERCY l). Boswmrru. a citizen of the United States. residing at Akron. in the county of Summit. and State. of Ohio. have invented new and useful Imru-uvernents in llims for \Vheels, of which the folh'minp is a speeifieatim'i.

.Th'is inu-ntion relates to improvements in rehiele wheels, more especially to the rim portion thereof. and the object of the invention is toprovide means for holding, a tirecarryingi rim (let:u-lial l r in position on the. peripheral portion ot a vehicle wheel, the meansfor clamping the tire-carrying rim on the vehicle wheel emhodyine means for laterally cmnpressing or distorting the base portion of an elastic tire seated on the tire carrying: rim so that the operation of securing: the tire-carr \'ing rim in position simultaneously ctl'ects a compression or distortion of the base portion of the tirc.therehy effectin in one operation two results which hare hecu heretofore accomplished hy two .inde pendentoperations, it being well known that the life and usefulness of an elastic tire is greatly enhanced by compressing or distorting the base of the rimengaging. portion thereof;

llitli the foregoing: and other ohjects in view, the invention consists in the novel eonstruction, combination and arrangz'enwnts of parts coustitutim; the invention to he hereinafter specifically described and illustrated in the accompanying drawing which forms a part hereof wherein is shown the preferred embodiment of the invention. but it is to he understood that changes, variations and modifications can he resorted to which com within the scope of the claims hereinafter appended.

The drawing presented is a transverse seetional view of the rim portion of a vehiele wheel embodying this invention, also showing a tire mounted thereon and the tireholding means in operative relation with respect thereto.

Referring; to the drawings in detail the reference numeral 1 indicates the folly of an ordinary vehicle wheel on which is mounted a peripheral telly-band 2. Extending circnmferentially and seated on the outer face of the fell band 2 is a broken annulus 3 approximately triangular in cross section. with 21v wide base approximating in width substantially the width of the felly-band 2 fttt'eS of the troken nd with a relatively narrow median portion 1 first of all roan end or. it;

from which the outer face of the hand inclin'es 1n hoth directions to the side edges thereof. and with the angles between the base and the faces -'lthereof Fox-mint an abrupt and an acute angle.

.tdapted to be mounted on the faces 4 of the broken annulus are apair of tireholding members 5 each prmided with an outer face (3 constituting when positioned a seat for a tire T and each also provided with an inclined inner face R adapted to engage one of the outer or inclined taxes 4 of the hroken annulus 5). The lateral portimis of the men'lher- 5 are prorided with out\ .'ardl extending tire-engaging: flanges a of a pre ferred type. that is to say, it the tire :3: he enuaged is provided with a hat s ltnown as a straigrl'it side the flanges a re shaped accord in l a shown. and i the latrral laces o the tire 7 are provided with ateral heads. the flanges 9 will he fashioned in the term of the conventional clen'hm' thingies to a comlnodate tln-mselvcs to the curved surfaces of the tire.

The memhers 5 are so arranged that when seated and with their inner inclin d faces S engaging the outer laces -l ol the lu'oken annulus ftlu inner or opposing edges of the nnanhers will he slightl separatml to provide a space ill. The wheel is provided, at intervals with suitahlc transverse apertures in whi h are mounted holts 11 pr vided with nuts 1;. in order to toree the members 5 oward each other there is pro-- rided on each of the lateral l'aces oi the wheel a cir uml'crentialtyextending; clamp ing hand 1 the outer portion ol' each ring; hein adapted t- "image the side t'ace of its respe tive lire-h ldinghand 5 and with its inner portion provided with a circunrferential ridge H dr'signetl to enga 'e on side oi" lhc heel. 'lhe circumt'ercntial ring l3 are provided with a series i apertures arranged to he positioned in registeria relation with respect to the apertures in the. wheel which receivethe bolts ll so that the holts ll may he passed through these three. registering a1wrtnrcsrnnl as the nuts 12 are drawn up the hands 3 are drawn toward each other and as their inner p rtions 14 engage the, wheel their outer pin-th ns engaging the members 5 will "tort-e the latter toward each other and as the memhers 5 are annular and their inner fa es 8 enga gr the annulus 3 the latte! i2 se if: the tell band and the wedging action set up by the lateral movements of the rim-forming members 5 toward each other tends to tighten them in position and prevent circumferen- 'tial movement thereof. At the same time, the lateral movements of the members 5 toward each other cause the flanges 9 thereof to compress or distort the base portionof the tire which is seatedon the outer face 10 of. these members, so that a duplex result is effected; that is to sa the rim-forming members 5 by being orced toward each other are clamped onto the member 3 which in turn is compressed or contracted onto the felly band, thereby effectually locking the rim-forming members 5 from movement and'tlie much-desired compression or distortion of the base of the tire is effected;

1. A vehicle wheel provided on the peripheral portion thereof with a circumferentially-extending broken annulus approximately triangular in cross-section, a pair ef annularly-formed tire-holding members seated on the inclined faces of said annulus,

the inner faces of said ti-re-holdingmembers fashioned to engage and cooperate with the inclined faces of said broken annulus and with outwardly-extending portions adapted to engage the base portion of a tire whereby when said tire holding members are forced toward each other said broken annulus is clamped on said wheel, said tireholding members are clamped on said annulus against movement and the base portion of the tire is compressed or distorted.

2. A vehicle wheel provided on the peripheral portion thereof with a circumferentially extending, laterally removable,

-10 broken annulus, approximately triangular in cross-section, a pair of endless tire-holding bands having their inner faces inclined to cooperate with the outer faces of said annulus and with their outer portions fashioned to engage the base portion of a solid tire, means having connection with the wheel 1 adapted to force said tire-holding bands toward each other to thereby simultaneously contract said annulus on said wheel, hold said tire-holding bands removably on said wheel and simultaneously compress or distort the base portion of a tire. v t

3. A' vehicle wheel provided on the eripheral portion thereof with acircum erentially extending, laterally detachable,

.broken annulus, approximately triangular in cross-section, a pair of tire-holding bands having their inner faces fashioned to cooperate with the outer faces of said annulus and with the outer portions thereof adapted toengage the base portion of a solid itire, a pair of annular rings arranged along the side faces of said wheel and constituting means for shifting said, tire-holding bands toward each other to thereby cause a contra ction of said annulus, a temporary looking of said tire-holding bands in. position, and a simultaneous compression or distortion of the base portion of the. tire.

4. A vehicle wheel provided on the peripheral portion thereof with. a circumferentially extending, laterally detachable,

broken annulus approximately triangular in cross section with the inclined portions thereof extending toward each other, a pair of annularly-formed tire-holding bands arranged to be seated on said annulus and cooperate therewith and with the outwardlyextending portion thereof fashioned to engage the base portion of a solid tire, and means to shift said tire-holding bands toward each' other, thereby clampingsaid bands on said annulus, contracting said annulus and simultaneously compressing or distorting the base portion of the tire.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses. 7
